1. Remove the cylinder head (see page 6-35).
2. Inspect the camshaft (see page 6-43).
3. Check the cylinder head for warpage. Measure
along the edges, and three ways across the center.
• If warpage is less than 0.05 mm (0.002 in.),
cylinder head resurfacing is not required.
• If warpage is between 0.05 mm (0.002 in.) and
0.2 mm (0.008 in.), resurface the cylinder head.
• Maximum resurface limit is 0.2 mm (0.008 in.)
based on a height of 121 mm (4.76 in.).
1. Remove the cylinder head cover (see page 6-34).
2. Loosen the adjusting screws (A).
3. Remove the bolts and the rocker arm assembly.
–1 Unscrew the rocker shaft mounting bolts two
turns at a time, in a crisscross pattern, to
prevent damaging the valves or rocker arm
